APPARATUS FOR EXTRACTING OIL.

SPECIFICATION forming part of Letters Patent No. 587,410, dated August 3, 1897.

Application filed April 3, 1896.

To all whom, it may concern:

Be it known that I, CORNELIUS S. Vos- BURGH, a citizen of the United States, and a resident of UnionCity, in the county of New Haven and State of Connecticut, have invented cert'ain new and useful Improvements in Apparatus for Extracting Grease, &c., from Wool, of which the following is a specification, reference being had to theaccom panyin g drawing, forminga part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to apparatus for extracting the grease, oil, and fat from wool; and the object of this invention is to provide improved machinery of this character by means of which a continuous circulation of the wool in the solvent is secured, from which it is passed through pressure-rollers and through heated rollers in a vacuum, and also the vaporized solvent is conveyed to a condenser, where the same is condensed and reused with but a minimum loss of the solvent;

' and with these and other objects in view the invention consists in the construction, combination, and arrangement of the parts hereinafter more fully described, and illustrated in the accompanying drawing, the same being a partial central vertical longitudinal section of the apparatus which I employ.

In the practice of my invention I provide a coil A, consisting of one or more coils of large pipe, to one end of which is connected a vertical stand-pipe A and at the top of which is secured a head A across which are mounted two parallel rollers A, upon which the wool is fed, and with the bottom or opposite end of the coil A connection is made with a vertical pipe A, which extends below the bottom of the coil A and with the opposite side of which is connected a pipe A, which communicates with a pump-casing A which casing is in connection by means of the pipe A with the upper end of the standpipe A whereby a continuous connection is formed through the stand-pipe A the coil A, the bottom of the pipe A thence into the pipe A through the casing A and pipe A back to the upper end of the stand-pipe A and it is through these pipes that the solvent is circulated by means of the pump within Serial No. 586,016. (No model.)

the casing A and as the wool passes between the rollers A the discharging solvent enters the stand-pipe through the pipe A and carries the wool downwardly into and through the coil A, as indicated by the arrow, upon the lower coil ofsaid coil A.

The upper part of the vertical pipe A projects into a closed casing or chamber B, and mounted in said casing above the upper end of the pipe'A is a shaft or roller 1), and at the lower end of said pipe is a similar roller b and mounted upon said rollers b and b is a belt b the body portion of which is composed of wire mesh or similar material which is provided with outwardly-directed teeth or projections Z), and it is against this belt that the wool submerged in the solvent is forced by the continuous circulation before referred to; but the main portion of the solvent passes through the mesh and into the pipe A, but the wool, being retained by the mesh, engages the projections thereof and is carried upwardly through the pipe A into the chamber B, and it will be observed that the dotted lines R in the stand-pipe A and the vertical pipe A indicate the level at which the solution in said pipes will stand. The lower side of the vacuum chamber or casing Bis also provided with a downwardly-directed tube B the lower end of which opens into a tank or receptacle B adapted to receive water and into which the wool is discharged from the vacuum chamber or receptacle B, and communicating with the top of the chamber or casing Bis a pipe 13*, the outer end of which is in communication with a condenser B with which is connected a vacuum-pump B.

In front of and a little below the upper end of the vertical pipe A and within the vacuurn-chamber B are two pressure-rollers E and E the lower rollers E being preferably of greater diameter than the upper roller, and between the rollers E and E and the upper portion of the elevator-belt b are two rollers F, in which is mounted a belt F and between the upper roller E and the roller 19 is a shaft G, provided with side plates or wings g, adapted to aid or accentuate the discharge of the Wool from the belt b upon the belt F from which the wool is conveyed to the pressure-rollers E and E In front of the rollers E and E are two hollow rollers H and 11 through which a current of hot water or steam is in continuous circulation from a suitable source of supply and which heats said rollers so that when the wool is received from the pressure-rollers E and E by means of the belt 72, carried by the rollers h, the remaining solvent retaining the wool is vaporized by the heat from the rollers II and H without injury to the fiber of the wool, which is occasioned by bringing the wool in direct contact with heated water or steam, as is well known to those who have made practical experiments of this character.

Outside of the roller H and adjacent to the side of the boX or casing B is a shaft or roller K, and just below the bottom of the roller H is a corresponding shaft or roll 7;, and below the bottom of the tube or casing B is a similar shaft or roller and another similar shaft or roller is mounted just below the roll H in the box or casing B, and mounted on the shafts or rollers K, 73, and k and on the heat-rollers H and H is a belt L, which is composed of wire or similar material, and said belt L is passed around said heat-rolls and said shafts or rollers in the direction of the arrows k Arranged below the shaft or roller 7t and adjacent to the bottom of the tank or receptacle B is a similar shaft or roller M, and at the right of and below the heat-roll H is a similar shaft or roller m, and a belt m similar to the belt L, is mounted upon the shafts or rollers M and m and moves in the direction of the arrows m Arranged below the shaft or roller E is a cup'shaped receptacle T, with the bottom of which communicates a pipe U, which is in communication with the vertical pipe A to convey the solvent which is pressed from the wool by the pressure-rollers E- and E back to the vertical pipe A By means of the vacuum in the casing or chamber B the water in the discharge-pipe B will be drawn upwardly therein to a point therein indicated by dotted lines referred to by the reference-letter R, and it will be also observed that the solvent in the pipe A and the water in the discharge-pipe B will seal this vacuum-chamber B and it will be impossible for the solvent to escape therefrom and commingle with the air, and by this means the volatilized solvent can be drawn through the pipe B into the condenser B by means of the vacuum-pump B and condensed with a minimum loss of the solvent.

I also provide a suitable receptacle or other device a adapted to be used as a solventsupply, and this receptacle is in communication with the upper part of the vertical pipe A by means of a pipe a so that the fresh solvent is maintained in the upper end of the vertical pipe A Thus the wool will be passed through a diluted solvent in the coil A to remove the greater portion of the grease and other matter therefrom, and during its elevation by the belt b it will be passed through the pure or fresh solvent in the upper end of the vertical pipe A before the wool reaches the pressure-rollers E and E I-Ieretofore it has been necessary to provide separate receptacles containing different grades of solvent, the first receptacle containing a solvent greatly diluted by the matter extracted from the wool during the first step of cleansing the wool and the second containing a purer solvent which removes more grease and other matter from the wool, and so on, while applicant passes the wool through two grades of solvent in substantially the same vessel and by means of the same mechanism.

The operation of the apparatus will be readily understood from the foregoing description when taken in connection with the accompanying drawing and the following description thereof: As before stated, the wool is received by the rollers A", from whence it is discharged into the upper portion of the standpipe A and is carried downwardly thereinto by the solvent discharged from the pipe A the solvent being forced upwardly into said pipe A by means of the pump within the casing A and the wool, being thus soaked with the solvent, will gradually circulate through the coil A, as indicated by the arrows at, and be discharged against the lower portion of the belt 11 the solvent passing through the meshes of the belt into the pipe A and the wool lodging thereon and being carried upwardly through the pure or fresh solvent at the top of the vertical pipe A over the rollers 11 in the vacuum chamber or casing B and being discharged upon the belt F carried by the rollers F, from which the wool soaked with the solvent is passed through or between rollers E and E thence upon the belt 7L2, which carries it to the heated rollers 11 and H thence upon the belt L around the roller H exposing the wool, which is received in a thin layer, to one-half the heating-surface of said roller, and from this roller the wool is discharged into the tank 13 containing the water, and all of the solvent extracted from the wool by the pressure-rollers is collected by the receptacle T and conveyed to the vertieal pipe A and reused, as before described.
